Despite the enormous amount of kinetic energy consumed by health equipment around the world, mere health equipment kinetic energy is not widely used. And in invention of patent document 1, no consideration was given to load change, and even if it was possible to generate electric power, it was insufficient as a health appliance.

  On the other hand, in Patent Document 2, a load is taken into consideration so that an exercise suitable for the physical strength of the exerciser can be performed. As the method, the output voltage of the generator is varied by adjusting the volume of the control device. However, the amount of power generation decreases due to the exercise load. Therefore, the applied exercise load is not efficiently used for power generation. Furthermore, stable power generation is not considered.

It is a schematic diagram of load switching to a flywheel by electrical connection control of a coil. It is another embodiment of coil electrical connection control. It is an explanation side view of the power generation type health appliance according to the present invention.

  Hereinafter, a power generation unit and a power generation type health device according to the present invention will be described in detail with reference to the drawings.

  As shown in FIG. 1, the power generation unit 1 according to the present invention includes a shaft that is rotatably held through a free wheel 5, a transmission means 27, a flywheel 12, a magnet 13, a coil 11, and a rotation. It consists of a total 14, a control device 15, and a storage battery 17, converts a human motion into a rotational motion via the transmission means 27, and generates electricity with the magnet 13 and the coil 11 using the rotational motion.

  The shaft includes a first shaft 3 and a second shaft 4 connected to the left and right of the freewheel 5 that rotates in one direction, and both ends of the shaft are rotatably held by the bearing 2. Further, bearings 2a are arranged on the left and right in the vicinity of the free wheel 5, and hold the first shaft 3 and the second shaft 4 to assist the rotation of the free wheel 5 and the stable rotation of the flywheel 12.

  The free wheel 5 is a one-way rotational drive mechanism used for a pedal portion of a bicycle. The freewheel of the bicycle has a ratchet mechanism or one-way clutch between the sprocket (chain wheel), which is a gear that transmits the combined power with the hub and chain, and transmits the power only in one direction, and the rotation in the opposite direction runs idle and does not output . The force from the pedal is transmitted from the sprocket to the hub. However, the wheel rotation force received from the ground due to the inertia of the bicycle is idled by this mechanism and is not transmitted from the hub to the sprocket, and the pedal does not rotate.

  Other one-way rotational drive mechanisms include a sprag clutch and a starter clutch used in a cell motor part of a motorcycle engine, which can be employed in the present invention.

  Here, the rotation in one direction input from the transmission means 27 to the first shaft 3 is output to the second shaft 4 via the free wheel 5 to rotate the second shaft 4. On the other hand, the rotation in the opposite direction input from the transmission means 27 to the first shaft 3 is not output to the second shaft due to the freewheel spinning idle. Thereby, the 2nd axis | shaft 4 rotates only to one direction.

  The bearing 2 can be exemplified by a rod-like one that stands up from the ground, a rod-like one that is suspended from the top, and that is erected on a square frame or plate that is horizontally placed on the ground. The bearing 2 may be installed in any shape as long as the shaft can be rotatably held and the position can be fixed. The power generation unit 1 can be appropriately changed depending on the installation location and usage method.

  The transmission means 27 is a rotation mechanism that converts an exerciser's motion into a rotational motion and transmits it to the shaft. For example, a rotating mechanism of a rotating belt of a running machine, a rotating mechanism of a wheel of an exercise bike, and the like can be exemplified. In FIG. 1, the transmission means 27 including the drum 6, the belt 7, and the winder 8 is shown as an example.

  The drum 6 has a cylindrical shape and is fixed to the first shaft 3. The drum 6 has a concave portion 6 a at the center of the side surface and rotates in the same direction as the first shaft 3. The belt 7 is wound around the side recess 6a. The drum 6 rotates by pulling out and winding the belt 7 and rotates the first shaft 3.

  One end of the belt 7 is wound around the recess 6a of the drum 6 and the other end is drawn by an athlete. The belt 7 is repeatedly wound around the drum 6 and pulled out (double arrow in FIG. 1) by the action of the athlete and the action of the winder 8 described later. The belt 7 is preferably made of a low-stretch material in order to eliminate loss of motion transmission, and examples thereof include a wire, a chain, and a leather band.

  Note that the shape of the drum 6 is appropriately changed according to the shape and material of the belt 7. When the belt 7 is a chain, a sprocket (gear) can be used as the drum 6. If the belt 7 is a timing belt-like material used in an engine, a rotating body is provided separately from the drum 6, the belt 7 is locked to the drum 6 and the rotating body, and tension is applied to rotate by friction. The method can be adopted.

  The winder 8 is a device that rotates the belt 7 in a direction in which the belt 7 is wound around the drum 6. A winding spring can be illustrated. In addition, here, the drum 6 and the drum 6 are separated from each other, but may be integrated. For example, an automatic winding type tape measure structure using a spring can be exemplified. If it is integrated, it becomes compact, but it is better to make it separate for maintenance.

  The magnet 13 is a permanent magnet and induces an electric current in the coils 10 and 11 described later according to Fleming's right-hand rule. Therefore, the magnet 13 is disposed close to the magnet at a position where the magnetic flux passes through the coils 10 and 11. Here, a plurality of coils 11 are arranged in the radial direction of the flywheel 12 while being embedded in the outer periphery of the cylindrical flywheel 12. Further, a magnet may be disposed on the side surface of the flywheel 12 and a coil may be disposed on the side surface (first, second axis 3, and four directions) of the fixture 13. The magnet 13 is preferably disposed at a position at which the rotation center angle of the rotating body is equally divided to prevent rotation blur of the rotating body.

  The flywheel 12 is connected and fixed to the second shaft 4 and rotates in the same direction as the second shaft 4. In general, a flywheel has the following functions. The first function is energy storage. By replacing electrical energy and steam engine energy with dynamic rotational motion, the energy itself is stored and stored, which is suitable for storing relatively large amounts of energy.

  The second function of the flywheel is to stabilize various movements. This is an inertial action of the flywheel. For example, when the rotation slows down, a force that suppresses and maintains the force works, and when the rotation is going to be fast, it tries to maintain the same rotational speed. Further, since the flywheel is a rotary motion, it also has a gyro function for stabilizing the rotation axis.

  The coils 10 and 11 induce current by the passage of the magnetic flux of the magnet 13. That is, it generates electricity. In order to fix the coils 10 and 11, in FIG. 1, the position of the flywheel 12 in the radial direction is within the cup-shaped fixture 9 that passes through the second shaft 4 and covers the flywheel 12 in a U-shaped cross section. Embedded in. Note that the fixture 9 for fixing the coil has a structure that can withstand electromagnetic repulsion and is preferably formed of a resin or a non-magnetic material. More preferably, it is a structure made of a magnetic material in consideration of optimum magnetic field line control.

  Then, both ends of the coil 11 are connected to the + terminal 17a and the-terminal 17b of the stored value via the wirings 11a and 11b, respectively. The current induced in the coil 11 is accumulated in the storage battery 17. In the state of FIG. 1, the connection (wirings 10 a and 10 b) between the coil 10 and the storage battery 17 is interrupted by the switch 16. The switch 16 cuts off / connects the electrical connection between the coils 10 and 11 and the storage battery 17 by the control device 15.

  When the switch 16 is switched in the arcuate arrow direction in FIG. 1, the coil 10 is also electrically connected to the storage battery 17, and the load on the flywheel 12 increases. Therefore, a load is also applied to the transmission means 27 that rotates the drum 6.

  The switch 16 may be provided for each of the coils 10 and 11, or may be provided so as to connect the coils 10 and 11 in series as shown in FIG. It is desirable to arrange the coils 10 and 11 and the magnet 13 so that the coils 10 and 11 receive a lot of perpendicularly incident magnetic flux that may be in the vicinity of the magnet 13. The arrangement is not limited to FIG.

  The tachometer 14 may be any device that measures the number of rotations of the second shaft 4, and examples thereof include a tachometer and a stroboscope. And the rotation of the measured 2nd axis | shaft 4 is output to the control apparatus 15 as the rotation signal 14a which is an electrical signal. The rotation signal 14a is used for rotational load control of the flywheel 12.

  The control device 15 receives the rotation speed of the second shaft 4 from the tachometer 14 as the rotation signal 14a, and responds to the rotation speed of the second shaft 4 based on the load pattern or load level selected by the exerciser. A load is generated in the operation of the magnet 13 provided in the flywheel 12, and the braking control of the rotational motion of the rotating body (here, the flyhole 12) including the magnet 13 is performed. As a result, the rotation of the flyhole 12, the rotational load on the first and second shafts 3 and 4, and further the exercise load of the exerciser.

  Here, since the flywheel 12 including the second shaft 4 and the magnet 13 exhibits the same rotation speed, the rotation speed of the second shaft 4 is used as the rotation signal 14a. However, the rotation speed of the flywheel 12 is used as the rotation signal 14a. Also good. Further, when the flywheel 12 and the magnet 13 are separated, the rotational speed of the magnet 13 may be used as the rotation signal 14a.

  As the braking control means, a control signal for controlling the opening and closing of the switch 16 is output to the switch 16 to control the electrical connection of the coils. Furthermore, the control device 15 can also measure the amount of power generated by the coil 11 and the magnet 13 and display it on a separate display unit.

  The storage battery 17 is a device that stores electricity generated by the magnet 13 and the coil 11. The generated electricity is of course rectified and stored. Note that the generated electricity may be used directly as electric power for the electric device without using the storage battery 17.

  FIG. 2 is a schematic diagram of load switching to the flywheel by electrical connection control of the coil according to the first embodiment. 2A is a schematic side view of the flywheel 12 and the fixture 9, and FIGS. 2B and 2C show only the fixture 9. FIG.

  As the flywheel 12 rotates, the magnet 13 embedded in the outer periphery thereof passes through the vicinity of the coils 10 and 11 to generate a magnetic flux change and generate power. The coil colored in gray means that it is electrically connected to the storage battery 17 (the same applies to FIGS. 3 and 4).

  2A to 2C, the number of electrical connections of the coil facing the magnet 13 increases. As the number of electrical connections of the coils increases, the action of braking the rotational movement of the rotating body including the magnet 13 increases.

  As shown in FIG. 2, in the coil electrical connection control, a small number of coils are electrically connected to the storage battery 17 at the early stage of the rotation of the flywheel 12, and more coils are connected when the rotational speed of the flywheel 12 is increased. Control is performed by the control device 15 so as to be electrically connected to the storage battery 17.

  As a result, when the same rotational force is applied to the flywheel 12, the rotational speed of the flyhole 12 is slower when the number of electrical connections of the coils is large than when the number of electrical connections is small.

  The more the electrical connection of the coil to the storage battery 17, the greater the effect of suppressing the rotation of the flywheel 12 and the exercise load on the exerciser increases. When a load is simply applied by a mechanical brake, the amount of power generation is wasted. By performing electrical connection control as shown in FIG. 2, the rotational load of the flywheel 12 can be used effectively for power generation. Power generation can be realized.

  FIG. 3 shows another embodiment of switching the load to the flywheel by controlling the electrical connection of the coil. FIG. 3A is a schematic diagram of the coil unit 18. FIG. 3B is a schematic side view of the flywheel 12 and the fixture, and FIG. 3C shows only the fixture 9.

  In the second embodiment, a coil unit in which a plurality of coils are stacked (inner coil 19 and outer coil 19a) at one place in the radial direction of the flywheel 12 of the fixture 9 and the number of turns of the coil can be electrically varied. Form. The coil units 18 are scattered in a plurality of locations in the radial direction of the flywheel 12 of the fixture 9.

  If only the terminals a and b shown in FIG. 3 (A) are electrically connected (on) to the storage battery 17, electricity is induced only in the inner coil 19, the terminals a and d are connected, and the terminals b and c are connected. If it is electrically connected (on) to the storage battery 17, electricity is induced in the inner and outer coils 19, 19a. That is, the number of turns of the coil can be electrically varied. Thus, by arranging the coils, it is possible to make more power generation in a small space.

  Next, the power generation type health device shown in FIG. 4 will be described as an example of the present invention. The power generation type health appliance 20 includes the power generation unit 1 according to the first embodiment, a frame 21, a backrest 22, a stopper 23, a rail 24, and a carriage 25.

Here, the frame 21 is a square frame, a plate, a lattice, or the like in which a bearing 2a is also suspended from a horizontal portion 21b between the left and right upright portions 21. And the standing part 21a and the bearing 2 of FIG. 1 are the same.

  A backrest 22 is connected to the horizontal portion 21b and serves as a stopper when the belt 7 is pulled as shown in FIG. The backrest 22 may be provided with a protection member 22a for protecting the head 26a of the athlete 26.

  A rail 24 is placed on the horizontal portion 21b. A horizontally movable carriage 25 is placed on the rail 24 via a pulley 25a. As shown in FIG. 4 (A), the athlete 26 grips the handle 7 a provided at the end of the belt 7 of the power generation unit 1 on the carriage 25.

  A stopper 23 is provided between the standing portion 21a and the carriage 25 to lock the foot 26b of the athlete 26. The athlete 26 locks the back of the foot 26b to the stopper 23, and then uses the belt 23a or the like to fix the foot 26b. The upper is fixed to the stopper 23.

  Then, as shown in FIG. 4 (B), when the exerciser 26 extends the foot 26b, the carriage 25 slides in the direction of the backrest 22 (FIG. Pulled out, the first shaft 3 is rotated, the rotating body including the second shaft 4, the flywheel 12, and the magnet is rotated via the free wheel 5 to generate electricity. An arcuate arrow in FIG. 4 indicates the rotation direction of the flywheel 12.

  Thereafter, as shown in FIG. 4C, the exerciser 26 slides the carriage 25 so as to approach the power generation unit 1 by contracting the foot 26b (in the direction of the left arrow in FIG. 4C). 7 is wound around the drum 6 by the action of the winder 8.

  At this time, the first shaft 3 rotates in the direction opposite to the pulled-out direction, but the second shaft 4 and the flywheel 12 continue to rotate in the rotating direction when the belt 7 is pulled out by the action of the free wheel 5. . And the flyhole 12 receives the braking accompanying electric power generation, and a rotational speed becomes slow.

  In addition, as shown in FIG. 4, when the flywheel 12 is enlarged in the case of a slide type, the belt 7 may be bent by a pulley. As a power generation type health appliance, various structures such as a structure in which the arm is pulled or pushed by the arm or rotated by the foot can be adopted.
